Abstract

Chiococca motleyana is a new name to replace the laterhomonymChiococca pubescens arising after the transfer of Asemnantha pubescens Hook. f. into the genus Chiococca against the earlier homonyms described by Humboldt and Bonpland ex Roemer and Schultes 1819, and by Standley in 1919. Asemnantha was separated from Chiococca by Hooker f. in 1873, based on its 4-merous flowers clustered into sessile axillary fascicles, against the 5-merous racemiflorous species of Chiococca P. Browne. Later on new Chiococca species were described having 4-merous flowers (C. henricksonii M. C. Johnston 1939, and C. petrina Wiggins 1981) and solitary flowers in the axils. With these new discoveries the morphological diagnostical differences disappeared between the two genera. Recently Motley and co-authors (2005) suggested the unit of the two genera based on the common clade obtained by molecular phylogenetic studies.
